Nexa Aurum EA V1.0 MT5 — Adaptive Grid for XAUUSD

Platform: MetaTrader 5 (MT5)
Pair: XAU/USD (Gold only)
Account Size: From $500 (recommended $1,000+)
Broker: ECN/RAW spread, fast execution (1:300–1:500 leverage)
Execution: VPS strongly recommended for stability

The Nexa Aurum EA V1.0 is a gold-exclusive Expert Advisor that blends grid mechanics with modern adaptive risk controls. Unlike fixed-step grid systems that collapse in strong trends, Nexa Aurum dynamically sizes grid steps using ATR-based logic with min/max clamps, ensuring the grid breathes with market volatility. Built-in equity and margin protection, daily loss guards, and strict layer limits make it safer for long-term deployment compared to reckless, open-ended grids.

Key Features

• Adaptive Grid Step (ATR-based)
  Grid spacing adjusts automatically to volatility.
• Min clamp: prevents overly tight spacing in calm sessions.
• Max clamp: ensures spacing doesn’t widen excessively during high volatility.
• Historical News Filter (Backtest Mode)
  Unique ability to test with vs. without news filter from 2020 onward.
  Useful for evaluating how gold reacts to CPI, NFP, FOMC events.
• Day & Session Filters
• Monday Rules: Option to skip or delay trading until liquidity normalizes.
• Friday Rules: Flatten positions before weekend gaps.
• Trading Hours Window: Define precise active session windows (e.g., London–NY overlap).
• Trading Modes (Optional)
  Choose between conservative, balanced, or aggressive templates.
• Account Protection
• Equity Stop: Shut down trading when equity drawdown hits threshold.
• Margin Guard: Auto close trades when margin usage is unsafe.
• Daily Loss Guard: Halts new trades for the day after hitting defined loss.
• Max Layers: Hard cap on number of grid levels to prevent runaway exposure.

Recommended Setup

• Broker: ECN/RAW spread with fast execution (tight spreads crucial on XAUUSD).
• Leverage: 1:300–1:500 for breathing room.
• Account Size: Minimum $500 (micro lots possible), recommended $1,000+.
• VPS: Dedicated low-latency MT5 VPS required.
• Symbol: XAU/USD only (this build is gold-exclusive).
• Timeframes: Works on any chart TF (logic is tick-driven).

Example Workflow

1. ATR-based grid spacing is calculated at start.
2. EA checks Monday/Friday filters and session timing.
3. If conditions are met, grid engine begins layering BUY/SELL trades.
4. Max layers + equity guard ensure the grid doesn’t spiral.
5. News filter blocks new entries near high-impact events.
6. Positions are closed via basket take-profit, daily guard, or protective equity stop.

Pros & Cons

Pros

• Gold-specific tuning (XAUUSD only).
• ATR-based step adjustment avoids rigid spacing failures.
• Full suite of protections: equity, margin, daily loss, layer caps.
• Historical news filter for realistic backtests.
• Monday/Friday & session controls.

Cons

• Still a grid system (drawdowns inevitable if misconfigured).
• Not multi-symbol; limited to gold.
• Requires VPS + strong broker execution.
• Higher learning curve compared to “plug-and-play” bots.

FAQ

Does it use martingale?
No. While it layers trades, lot sizing can remain fixed or progressive, but no uncontrolled martingale.

Can I trade other pairs?
No. This build is gold-only (XAU/USD).

Is it prop firm compatible?
Partially. Depends on firm rules — many disallow grids due to potential DD. Use conservative templates if attempting.

How many layers should I use?
Start with 3–5 max layers; never allow unlimited stacking.

What about weekend safety?
Friday rules can be enabled to flatten trades before close.

Final Thoughts

Nexa Aurum EA V1.0 MT5 is a carefully engineered adaptive grid system for gold. By combining ATR-driven spacing, built-in equity/margin guards, news-aware backtesting, and strict session filters, it’s far safer than traditional “set and forget” grid bots. Still, it remains a grid strategy — use VPS, strong brokers, and conservative settings. Best suited for traders who understand gold’s volatility and want a controlled, disciplined grid approach.
